Patent DE-19747564-A1 (DE)
Title: Fuel injection control arrangement for petroleum combustion engine
Inventor: HOSOYA HAJIME
IPC: F02D41/38
Filed: 1997-10-28
Abstract: The arrangement includes a fuel injection valve for a direct injection of fuel into a combustion chamber of the engine, whereby pulse lengths of an injection pulse signal which is to be output to the injection valve, are corrected in response to a pressure of fuel which is supplied to the injection valve.  A calculation arrangement (B) is provided for calculating the pulse lengths of the injection pulse signal based on operating conditions of the engine. An aperture control arrangement (C) corrects the calculated pulse lengths under the assumption, that the pressure of fuel which is to be supplied to the injection valve equals a predetermined reference pressure. A fuel pressure detection arrangement (E) determines the pressure of fuel which is to be supplied to the injection valve, and a regulation arrangement (D) corrects the calculated pulse lengths in response to the determined fuel pressure. A pressure condition discriminator arrangement (F) decides, whether the fuel pressure is to low or to high, and a control switching arrangement (G) activates the aperture control arrangement if the fuel pressure is to low and/or to high.

Title: Multi level fabric stenter for heat treatment
Inventor: JODELEIT REINHARD
IPC: D06C3/02
Filed: 1998-01-16
Abstract: The multilevel stenter has one deflection point (10a) within the fabric heat processing zone (3) which has at least one deflection wheel (11,12) which can be adjusted in relation to the other on the longitudinal line of the stenter machine (1), forming part of the fabric web alignment system (19). The fabric alignment system (19), within the heat treatment zone (3), has a leading deflection point (10a) in the fabric transport system (4) in the direction of fabric travel which deflects the carriers (7a,7b) together with the fabric (WB) from the first level (3a) into the second processing level (3b). An adjustable deflection wheel (12) at the first deflection point (10a) can be set against an angled draft action on the fabric edge (8a) in parallel to the moving length section of the fabric (WB). A linear setting drive (11a,12a), for each adjustable deflection wheel (11,12), has a setting movement path (x/2) according to the set angled drafting value (x), controlled according to the angle of the fabric carriers (7a,7b) round the deflection wheels forming part of the path of the set angled drafting value (x). The setting movement path (x/2) of the linear setting drive (12a), acting on only one deflection wheel (12), is by only one-half of the angled drafting value (x). When adjusting both deflection wheels (11,12), the setting movement path is one-quarter of the angled drafting value (x). The fabric support level (7a, 7b') of the two fabric carriers (7a,7b) pass round the deflection wheels (11,12) of the first deflection point (10a) by about 180 deg . At the fabric exit (6) from the stenter, the fabric carriers (7a,7b) are returned round deflection wheels (15) to the fabric entry  (5). The deflection wheels are on a common shaft (15a) in a synchronized action through a common drive. The deflection wheels (11,12) at the fabric entry (5) and at each deflection point (10a-10c) within the heat treatment zone (3) rotate freely, independently of each other. Deflection wheels (17a,17b) are at the fabric entry of each stenter for the fabric carriers (7a,7b).
